Flying the pattern at S40

Prosser is non towered, so the pattern is self announced on CTAF 122.8. AC 90-66B asks for a report on entry and on each leg, and for the standard 45° entry to downwind at pattern altitude.

Watch the right traffic ends here: 26. A right pattern at a field where the other end is left is the single most common place to end up pointing at opposing traffic. The full entry procedure is here →

More about S40

Pattern direction and alignment are drawn from the FAA NASR (28-day cycle); the diagram is generated, not an FAA chart. Pattern altitude is shown as published where NASR carries one, otherwise as the AC 90-66B 1,000 ft AGL convention. For planning and education only; always verify against the Chart Supplement.
